how much GH calmag are you running with your RO water?

on the bottle it says to run 1ml per liter, if using RO water add 1ml per liter before adding nutrient solution. so im assuming i would be running 8ml per gallon with RO? i don't mean to sound like a complete airhead, ive just switched from botanicare calmag (got a good deal) and i was only using 6 ml per gallon and i had great results.

Well in the uk 1 gallon is 4.5 litres so you'd be using 4.5ml but a us gallon is 3.8 litres so only 3.8ml :)

I add just enough so that my r/o water reads 100ppm. For example say that you have 4 gallons of water and your ppm reads 10 from the water well I add enough to get to or close to 100 ppm. Then I add my nutes (house of garden)

Thanks for the replies fellow smokers. Im switching back to botanicare, i used half of what they recommend and i never had a problem. With GH im adding more than theyrecommend and its not enough. Nothing against GH, ill just go with what i know.
